SPECIFICATION forming part of Letters Patent No. 450,378, dated April14, 1891.

Application filed December 24,1890. Serial No. 375,716. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM H. ROBINSON, a citizen of the United States,residing at Oceanside, in the county of San Diego and State ofCalifornia, haveinvented a new and useful Ink-Eraser, of which thefollowing is a specification.

My invention relates to an improvementin ink-erasers; and it has for itsobject to provide a simple and inexpensive article made in variousgeometrical forms that will efficiently take the place of the ordinaryeraser, and at the same time to combine with the eraser a blotter thatwill be handy and convenient in blotting where the erased portion iswritten over.

Referring to the accompanying drawings,-

Figure 1 is a perspective view of a hexagonal ink-eraser constructed inaccordance with my Figs. 2 and 3 are similar views Fig. 4 is a sectionalview.

suitable material cut on its periphery to form a hexagonal triangulardisk or any other preferred geometrical block. Around the entireperiphery of the figure is glued a strip of abrasive material B,composed of flint-finishing paper, emery, or other suitable abrasivematerial, or the figure may be coated with abrasive material, ifpreferred. On the faces of block A and flush with the edges of theabrasive strip are secured pieces of blottingpaper 0, which combine inthe block both an ink-eraser and blotter. A slight pressure issufficient to remove the ink in this article, and the paper by the usethereof is left comparatively smooth and is easy to rewrite over, whilethe blotting-paper on the faces of the block serves the function of ahandy and easy blotter to blot readily the portion written over andpreventing any possibility of the ink spreading before it can beblotted.

Having described my invention, what I claim, and desire to secure byLetters Patent, is

In an ink-eraser, a geometrical block having its entire peripherycovered with a strip or coating of abrasive material and its faces withblotting -.=paper, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two Witnesses. I

WILLIAM H. ROBINSON. Witnesses:
